Displaying Logo from Uboot

Hi Team,

My processor: RZG2N

Package: VLP3.0.5 (RZ/G Verified Linux Package v3.0.5-update1(RTK0EF0045Z0021AZJ-v3.0.5-update1.zip)

I have a requirement to show the uboot logs and especially a Logo of my client when the system is in uboot. Since it take couple of seconds to reach the user space and the drivers to be active, we need to show a logo on our LVDS display screen as soon as the system turns on. 

I have a rough Idea on what to be done. I have explained my idea below.

  1. We need LVDS display driver in UBoot for driving the display. (I have no idea if this is already there or not)
  2. Touch driver is not necessary since inputs are not allowed at this stage.
  3. PWM lines from processor should be active.
  4. A logo should be there is any of the flash memory so we can show that is LVDS display.

Please provide an example on how to achieve this. Since I have very low experience I am not sure about the above points.

Please let me know if something is missing.

Thanks in advance,

Kartha.
